ANDERSEN, OF WATERBURY, CONNECTICUT JAR R VASE ANCHOR FOB, ELECTRIC LAMPS T: Application filed Mayll, 1928. Serial No. 276,930;

This invention is a novel construction of that the cover 13 will be sized and shaped to, anchor device employed for securing an elecfit the mouth of the jar or vase and the detric lamp to a jar, vase or other hollow arpending portion of the shell 11 is merely in-v ti'le. 1 serted through the central opening. By this 7 The ohject of the invention is to provide arrangement the anchoring device can be, a cheap and simple form of device by means used in connection with various sizes and of which an, electric lamp can be connected shapes of covers conforming to the shape to a jar or vase without necessitating the borand size of the jar or vase.

In the practical embodiment of my invens 1 L indicates the jar or vase-to whichit is ti on I employ a rod 10 carrying a nipple shell desired to connect the electric lamp and in so 11 at. itsvupper end and to which the socket, which the anchoring device is located. I 12 of an incandescent lamp is connected, the In operation, the depending threaded rod nipple shell 11 constituting a wiring box havis passed throughthe central opening of the ing an opening 11 produced therein and cover and the depending bushing 11 of the through which the conductor wires 12*,leadwiring box 11 is fitted into said opening.

mg to the lamp may pass. .This shell 11 The member 15 carrying the anchor rods is also has :1 depending bushing 11" which then threaded upon the threaded end of the is adapted to be passed through the central depending rod or stem 10 The depending" openingof a cover 13 resting upon "the mouth rod 7 or stem with anchor rodsis then inof the jar or vase. It will be understood sorted into theinterior of the'jar or Vase, l0

and this can be accomplished either by holding the rods in upright position and passing them downwardly through the top of the jar or vase or the device can be inverted and likewise the jar and the jar lowered over the anchoring rods. The jar and device will then be inverted. After the anchoring device has been inserted in the jar the anchoring rods immediately fold outwardly, as indicated in full lines in Figs. 1 and 4 and dotted lines in Fig. 3. The wiring box is then rotated causing the rod or stem 10 to rotate and the member 15 to move upwardly, forcing the outer curved and cushioned ends of the anchor rods into binding engagement with the interior of the vase or ar. I

The outward movements of the anchor rods will be limited by the depending per-- tions of said rods engaging the rod carrying )member and their inward folding movements will be limited by the stop lugs car- By employing three.

' anchored in the jar or vase and movement of the'lamp in any direction will be effectively prevented.

In order to remove the device from the jar or vase it is only necessary to rotate the wiring box and the rod or stem 10 in the appropriate direction to carry the member 15 downwardly into the jar or vase and then by inverting said jar or vase the anchoring rods will fall by gravity to positions substantially parallel with the threaded stem and then the jar or vase can be lifted clear of the anchoring device.

By means of a device constructed as herein shown and described it is possible to quickly and easily connect an electric lamp to any typeof jar or vase without boring the jar or vase to. accommodate the conductorwires, it being necessary only to provide some suitable cover through which the depending stem can be inserted and arranging that cover upon the mouth of the jar or vase as most cslearly shown in Figs. 1 and 4:, Having thus described my invention, what Iclaim is I 1. An anchoring construction including a centrally threaded plate member, a plurality of pivot ears turned up from said member to form bearings, a stop lug turned up adjacent one end of each bearing, an abutment adjacent the. other end of'each bearing, an anchor rod extending through each bearing and being bent at substantially right angles adjacent each end of thebearing, one portion of said rod being adapted to cooperate with one of {said abutments to limit motion and another portion being adapted to engage one of said stop lugs.

I centrally threaded plate member, a plurality of pivot ears turned up from said member to form bearings, a stop lug turned up adjacent one end of each bearing, an abutment adjacent the other end of each bearing, an anchor rod extending through each bearing and being bent at substantially right angles adjacent each end of the bearing, one portion of said rod being adapted to cooperate with one of said abutments to limit motion and another portion being adapted to engage one of said stop lugs, said abutments and said rods being so related that said abutments stop said rods short of a horizontal position,

3. In a lamp anchor, a receptacle having a restricted upper portion, a cover for said receptacle having a central opening, a hollow wiring box having an internally threaded bushing extending through said opening and having a cable receiving opening therein above said cover, a lamp socket mounted on the upper end of said wiring box, a stem threaded into said bushing and having a threaded lower portion, a threaded member received on said lower end and carrying a plurality of pivotally mounted anchor arms. l. In a lamp anchor, a receptacle having a restricted upper portion, a cover for said receptacle having a central opening, ahollow wiring box having an internally threaded bushing extend ng through said opening and having a cable receiving opening therein above said cover, a lamp socket mounted on the upper end of said wiring box, a stem threaded into said bushing and having a threaded lower portion, a threaded member received on said lower end and carrying a plurality of'pivotally mounted anchor arms,

and stops on said member serving to maintain sa d arms in anupwardly inclined. position. said threaded member including a single blank portion including pivot ears, stop lugs and abutments. formed thereon, said stop lugs being disposed one adjacent one end of each pivotear and said abutments being disposedside thereof and provided at its upper end with an external thread for'the reception of a lamp support and having its lower end provided with an internal thread and having intermediate such threaded upper and lower ends a lateral opening for the reception of the conductor wiresleading to the lamp socket terminals, a stem or rod threaded into the lower portion of said wiring box and having a lower threaded portion,a member adjustably mounted upon such lower threaded portion, a plurality of anchor rods. pivotally connected to said member, the said member having means for limiting the outward folding movement of said rods. I

6. In a device of the kind described, the combination with a cover, of a wiring box having an internally threaded bushing passing through said cover, said wiring box carrying a lamp socket at its upper end, a rod or stem threaded into the said bushing and having a lower threaded portion, a member adjustable upon said threaded portion, and a plurality of anchor rods pivotally connected to said member, said member having means for limiting the inward folding movements of said anchor rods, said anchor rods having means for limiting the outward folding movements of said rods.
